摘　　要：为给微型电动车的参数优化设计提供参考,选定轮毂电机驱动的微型电动车作为研究对象,综合考虑了城市道路交通状况、城市居民日常出行和成本等因素,通过动力学计算、MATLAB/Simulink仿真等方法对微型电动车关键性能参数合理范围的选择进行探讨,包括最高车速、电机类型、电池容量和续驶里程等。结果表明:微型电动车最高车速合理范围为80～100km.h-1,采用直接驱动的轮毂电机作为动力源,微型电动车续驶里程的合理范围为100～120km,对应的电池容量为12～14kW.h。To provide a guideline for the parameters optimization of micro electric vehicles, the selection of key parameters of a micro electric vehicle, including maximum speed, in-wheel motortype, battery capacity and mileage per charge was studied based on vehicle dynamics calculation and MATLAB/Simulink simulation, with the urban traffic conditions, daily driving requirementsand cost considered. The results show that the maximum speed of the micro electric vehicle should be set at 80-100 km · h^-1 the direct-drive in-wheel motor is selected to be the powertrainand the mileage per charge is set to be 100-120 km, which corresponds to the battery capacity of 12-14 kW · h.
